Re: [cdt-dev] How to get definition of a declaration that is in a header

[Krishna Narasimhan <krishna.nm86@xxxxxxxxx>]

I basically want to perform some renames of the declaration, find the structure and make some renames of the members inside the struct. Basically refactoring of the declaration, then find the definition and perform some refactoring there.

CDT does not keep ASTs for files in the index. It creates an AST for a file during indexing, saves information from the AST into the index, and then discards the AST.

Therefore, you have two options:
  1) Get the information you want from the index.
  2) Re-parse the header file to get an AST for it.

Depending on what it is exactly you want to do, one or the other may be more appropriate.
